Application led August 8, 1907. Serial No. 387,641.

To dZZ'whom-'it' may concern; `Be it known that we', PAUL SAsso, a citinen of. the, United` States, and JOHN P.

-FARUGA, a vsubject of the King of Great Brita-in, both residents of Alexandria, Egypt,

' have invented a new and Improved VVat'erheated.. i j

- While the .specification` describes the 'd e'- vice asemploying liquid fuel, it may be used *with fuels ofany kind.

'Hen-ter, yof whichy 'the following is' a full,

clear, andexact lescription. v

This invention relates to water heaters,

and .the 'object of t-he invention is to produce a heater having alarge heating surface, to the end that the water will become The invention. consists in the construction and combination of parts to be: more fully describedy hereinafter and particularly set forth in the claims. j

Referenceis .to be hadto the acccmpanying drawings forming 'a part of this speci Afication, in which similar characters ,of'refeny A ence indicate corresponding parts in all the figures.

Figure 1 is' a vertical central section through a heater constructed according to our inventionfthe lower portion of the figure being shown .inv elevation; Fig.. 2 isa plan of a -bell which constitutes a feature of the' invention; and-Fig. v3 is a plan of a battle disk or .draft disk which controls the flow ofv the gases of combustion .as'they pass upwardly lfrom the burner.-

Referring more particularly to :the parts, 1 represents the body `of the device, which is preferablyof cylindrical form as shown, and

formed ofan outer shell 2 andan linner shell 3, forming fa waterv jacket therebetween as illustrated. The iower portion of the body" is expanded to fornia base 4 mountedr upon'.

suitable legs as indicated. In lthe upper portion ofthe body a transverse double walled-head 6A is. provided. In the upper portion of the body 1 and centrally disposed therein, there is mounted a Hue 7 which is ofconical form as shown, the upper en( of :the cone'being cut off. `Tl1is .cone is formed with a double'wall present-ingl an outer shell- 8 and3 an inner shell 9iforming a water jacket therebetween. cone or flue is .in communication withthe water head 6 through the medium of a cir- VAculation pipe 10. In the lower portion of .the body a burner 11 provided, which is supplied with liquidfuelffrogn a...4 suitable? quickly The, lower portion. o f thisreservoir 12 attached at the .side of the base as indicated.

' In the lower end ofthe flue or 4cone 7 a. bell 1 3 is suspended; the lower edge of this. .bell lies around the outer edge of the burner- '11, and the belloperates as a guide to direct the gases-of combustion upwardly through Athe line or cone. The burner 11 is simply of cylindrical form7 having a plurality of openings 14 through which the fuel escapes-'and at which the ignition takesplace.

- The upper `end of the bodyA 1 v is lformed into a bonnet 15' having an upwardly pro-` jecting centralneck 16,said neck being provided with a- 'transverse bar 17. From the centralpoint of 'this bar a Asuspending wire 18 is'provided, which hangs vertically down wardinto the interiorof 4the cone or -tlue 7.

.Near the lower portion of the flue this wire supports a 4battle disk or flue plate 19, the

form of this platebeing clearly shown in- Fig. 3.' It is of circular'form, provid'edwith a serrated l'edge 20 and having a plurality of openings 21 distributed through its body. The wire 1S extends below the plate and af fords means for supporting the bell 13. To

facilitate this arrangemenuthe bell is provided with a transverse bar 22 similar to.- the bar 17 referred to above. The water passes into the water jacket of the body 1 through an inlet pipe 23, and the water s-,drawn olf' .from the device'through an outlet pipe 24 which passes out ofthe body on the opposite Side.

This pipe 24 is disposed in avloop or located within the upper portion of the conel andabove the baille plate' 19. It will be ob-` served that the upper portion of the 'cone is not directly in communicationwith the interior of the water head 6. The coil or loop 25 is attached to the upper extremity of the cone, sothat the water whichv passes from the device is drawn off at this point. In this yway, on account of the lack of direct communication between the cone' and thegh'ead atthis point, the water vis made to circulate down through the'pipe l()l into the lower por-` tion of the cone, whence vit moves upwardly 'before-being drawn off throughthecoil-Q.

In this way it will be observed' that -the .water is heatedmethodically for it will be understood that the coil 25 is located at the coil'25, of substantially triangular form, i

hottest'point in thel entire course of' the water. The'ba'ftle plate19 restricts the .up-

ward-How. of :the hot gases 'of oem'bustioir andieperates'toi force the principal portionv of the gases to pass the plate at the serrated edge., In this way the gases are madegto come closelyin contact with the innerwall, ofthecone.

The construction of the device is such as to stimulate the .circulation of thewaterto#V ward the delivery pipe 24. -This willnbe evident lfrom a consideration of the operation of. the conical flue 7 vThe 'water is admitted at the lower end of this flue, and as it boils,

the upward movement of the steam tends vto produce an upward'current of the water in the cone. In this way an upward circulation is induced, which tends to draw in the water vfro1nt he,'water head,1 and operates to deliver -the'water from theupper end vofthe cone to the pipe-24.v It is evident, also, that the water 'iny the iue will have a higher temperat ture than the water in the jacket'of the body, l

or inthe water head, and hence, the water which,v passes through the device is' heated in a most advantageous manner.- This'tend--,

. ency of the device to produce a circulation is especially valuable where the heater is usedin a heating system of pipes, and where the'water which' is delivered to the pipe 24 eventually returns through the pipe 23.

Special attention is called to the fact that. in this water '-heater the Awater .is 'heated methodically, that is, it is presented irst to heating surfaces which are not heated to the highest extent,y it then passes to more -highly heatedsurfaces, 'and is finally subjected to fthe highest temperature in the coil 25, which 'coming water, receives less heat `than `the is disposed in the flue', where' the heat is' concentrated.- Atthis point the area of .the

heating surface 4is very high as compared with the volume of the tube orA coil.v A

It will be evident that the water jacket around thebody which first receives the inwater -head 6. It is also evident that the water jacketed flue 7 receivesmore heat than the water lhead, and at the coil or loop 25 through which the water passes from the flue, the water receives the most heat. At tention is also called to the fact that the vconnection of the coil or loop 25 to the flue, is made at the upper end of the flue so that the ebullitionl of the water in the flue jacket will i tend to produce an upward movement of the f water'in the Hue, and in this way the, outf' ward-circulation of the water through the loop is assisted..

If the devicei to be used with a solid fuel,

instead of employing a burner 'such asl that .pl-shown, a grate or fire pot will be arranged -in the device at substantially the sam-e location as the burnerillustrated. g

Having thus described our inventionwe claim as new and desire to secure by Letters Patentr, t t, f
